Police investigating the suspected murder-suicide of a family of four in Mosman Park say a second handwritten note found at the scene may provide critical insight into the heartbreaking circumstances behind the tragedy.

The note reportedly contained the line: “We can’t continue to watch our baby suffer…,” a sentence authorities say is now central to understanding what happened inside the family home where Mai, Jarrod, and their two teenage sons were found dead.

Investigators have described the discovery as significant, emphasizing that the message appears to reflect years of exhaustion, despair, and emotional strain that remained hidden from those outside the household.

According to police, the note was located during a detailed forensic examination of the home, separate from an earlier message already acknowledged in the case. While authorities have not released the full contents of either note, they confirmed the second document is being treated as critical evidence.

The wording, police say, suggests a prolonged period of suffering that was not publicly visible. Investigators caution, however, that written statements must be interpreted carefully and within the broader context of forensic, psychological, and circumstantial evidence.

The deaths shocked the close-knit community of Mosman Park, a coastal suburb where serious violent incidents are rare. Neighbors and acquaintances have described the family as private, with no obvious outward signs of crisis, making the revelations in the note particularly difficult to comprehend.

Authorities have reiterated that the investigation remains ongoing and that no final conclusions have been formally announced. While the case is being examined as a suspected murder-suicide, police stress that determining motive requires careful analysis and confirmation of all evidence.

Specialist units, including homicide detectives and forensic psychologists, are assisting in reviewing the notes, digital records, and scene findings to reconstruct the sequence of events leading up to the deaths.

The line referencing a child’s suffering has raised complex and sensitive questions, including the nature of that suffering and how long it may have gone unrecognized. Police have not disclosed whether medical or other supporting evidence has been identified, citing privacy considerations and respect for the family.

Officials have urged the public to avoid speculation and to allow investigators to complete their work. They also acknowledged the broader conversation the tragedy has sparked around mental health, caregiver exhaustion, and the hidden pressures some families face behind closed doors.

For now, investigators say the second note represents a key piece of the puzzle — one that may finally shed light on a tragedy defined by silence, pain, and unanswered questions.
